use in webpack 4.x
I have the same bug and I found out that the behavior depends on the console window's width. According to the respective width, webpackbar can behave as expected, behave like shown in the GIF above or behave like shown in the GIF above but with more and more instances of the bar instead of increasing space (0% > 1% > 2% and so on… every update is rendered in a new line).
In my case
and Visual Studio Code (integrated terminal) on Windows 10. But the same goes for the native cmd on Windows.
Thanks for any feedback on this.
